Tenancy Agreement Northern Ireland

There Is No AST in Northern Ireland

If you have been searching for an assured shorthold tenancy agreement for a Northern Ireland letting, stop. Assured shorthold tenancies are a creature of English and Welsh law under the Housing Act 1988. They do not exist here.

Private residential lettings in Northern Ireland are governed by the Private Tenancies (Northern Ireland) Order 2006, as amended by the Private Tenancies Act (Northern Ireland) 2022. The tenancy you grant is a private tenancy — not an AST, not a short assured tenancy (that is Scotland), and not a residential tenancy under the Republic's RTB system.

This distinction matters because downloading a generic "UK tenancy agreement" from an online template site will almost certainly reference legislation that has no standing in Northern Ireland. Section 21 notices and Section 8 grounds do not apply here; deposit protection has separate Northern Ireland deadlines and penalties, including a fixed penalty equal to three times the deposit for a failure to protect it.

What Your Agreement Should Cover

Northern Ireland law does not prescribe a mandatory tenancy agreement template the way some jurisdictions do. You can use a written agreement in any reasonable format, and oral agreements are technically valid (though proving the terms later becomes nearly impossible). A written agreement should cover:

• The address of the property and the names of all tenants
• The start date and whether the tenancy is fixed-term or periodic
• The rent amount, payment frequency, and payment method
• Which party is responsible for domestic rates (governed by the property's Capital Value — if £150,000 or less, you as the landlord are liable by law regardless of what the agreement says)
• Deposit amount (capped at one month's rent since April 2023) and which scheme protects it
• Repair obligations — the 2006 Order already sets the statutory minimum, and your agreement cannot reduce the landlord's obligations below that floor
• Rules on alterations, subletting, and pets
• How and when either party may end the tenancy

The Tenancy Information Notice Adds a Parallel Duty

Even if your written agreement covers every detail, you still have a separate statutory obligation to serve the Tenancy Information Notice within 28 days of granting the tenancy. The TIN is a prescribed form under the Tenancy Information Regulations (NI) 2023, and it must include your name, contact details, emergency contact, agent details if applicable, rent amount, deposit information, and rates responsibilities.

The TIN is not a substitute for a tenancy agreement, and a tenancy agreement is not a substitute for the TIN. You need both.

Failure to serve the TIN within 28 days is a summary offence carrying a fine up to £2,500, and it becomes a continuing offence if you still have not served it 14 days after conviction or fixed penalty payment.

Variation Requires a Written Notice

When any prescribed term of the tenancy changes — a rent increase, a change in payment method, an amended repair clause — you must serve a Notice of Variation within 28 days of the change taking effect. This is another prescribed form under the 2023 Regulations.

Serving the Notice of Variation documents the change, but it does not replace the requirement to get proper contractual consent or, in the case of a rent increase, to follow the 12-month frequency rule that came into force on 1 April 2025.

Fixed-Term, Periodic, and Renewal

A fixed-term tenancy runs for the agreed period and then either ends or rolls into a periodic tenancy (usually month-to-month). Northern Ireland does not have automatic statutory periodic tenancies in the same way England does — the mechanics depend on what your agreement says.

If you grant a new fixed-term to the same tenant, the 12-month rent increase clock does not reset. The legislation treats a renewal with the same tenant as a continuation, not a fresh start.

Getting It Right From the Start

The tenancy agreement sets the commercial relationship. The Tenancy Information Notice, the Rent Book, the deposit protection, and the safety certificates are the statutory layers on top.
